Kai: I think this issue might be the same as the one that I'm encountering in my post yesterday titled, "Postfix not using LMTP Transport in map".
Can you look at your logs and see if you're getting a similar message to what I have below? Host postfix/lmtp[22981]: C0EEEA8: to=<mailman3:[127.0.0.1]:[hidden email] <http://postfix.1071664.n5.nabble.com/user/SendEmail.jtp?type=node&node=102395&i=0>>, orig_to=<[hidden email] <http://postfix.1071664.n5.nabble.com/user/SendEmail.jtp?type=node&node=102395&i=1>>, relay=Host.TLD[private/dovecot-lmtp], delay=566, delays=566/0.04/0.01/0.01, dsn=5.1.1, status=bounced (host Host.com[private/dovecot-lmtp] said: 550 5.1.1 <"mailman3:[127.0.0.1]:8024"@Host.TLD> User doesn't exist: mailman3:[127.0.0.1]:[hidden email] <http://postfix.1071664.n5.nabble.com/user/SendEmail.jtp?type=node&node=102395&i=2> (in reply to RCPT TO command)) Basically Postfix is reading the map, but applying it to the "To", but not using the relay for it at all. Instead it refers to the private/dovecot-lmtp in my case as the relay. Does this match the behavior you are seeing?
